Apostro: Morpho and Euler Vault Curator Explained

Apostro describes its business as kick-starting and curating on-chain money markets, each built around a specific trading strategy ¹. Its blog dates back to late 2022. It includes a 2023 deep dive on economic risk and risk parameters and a 2023 announcement about expanding to Arbitrum ⁵. The homepage names Lemniscap, Coinbase and Inception as backers, but doesn't give a round size or date ¹.

The legal setup differs by document. The 2022 website notice is issued simply by "Apostro" ⁴. The vault notice, updated November 10, 2025, says you contract with Salsa Labs Corp., a Panamanian company ³. That notice:

• limits use to people acting "in a professional capacity," not as consumers;
• excludes sanctioned persons and people in jurisdictions where vault use is prohibited;
• applies English law, with binding LCIA arbitration in London and a class-action waiver;
• caps the company's liability at US$1,000 or six months of vault charges, whichever is greater ³.

Apostro also builds Vera, an AI-agent toolkit for researching smart contracts ¹.

On Morpho, the curator sets a vault's allowed markets, supply caps and fees, and appoints allocators. Most of these changes take effect only after a timelock. A guardian (V1) or sentinel (V2) can veto risky pending changes ¹⁴. Apostro's Morpho vaults use a 3-day timelock ⁷. Its vault notice says the company sets the "Vault Parameters." It also says Apostro doesn't fully audit or monitor the third-party protocols, tokens and oracles the vaults rely on ³.

Morpho, as of October 23, 2026 ²⁷⁸:

The VCHF vault lends Swiss-franc stablecoins against cbETH and cbBTC ⁸. Apostro's site also names a USDe market, which lends against Ethena collateral ²⁸.

Euler. Third-party tracker TradingStrategy lists three Apostro-curated Euler vaults: USDC Core on Ethereum (peak about $10 million), Resolv on Base and a BNB Chain vault. Each charges a 10% performance fee and no management fee ¹⁰. These figures weren't checked against Euler's own app.

Apostro is paid through the vault performance fee, a share of the interest depositors earn. That fee is 10% on its active Morpho vaults, with no management fee ⁷. There's no deposit or withdrawal fee from the vault contract itself, but network gas applies.

• Collateral risk. A vault is only as safe as the collateral its markets accept. Apostro's Resolv vaults were built to lend against Resolv's USR, wstUSR and RLP tokens, and against aprUSR, Apostro's own USR vault token ⁸¹³. When USR failed, those markets were left with debt that couldn't be liquidated ¹².
• Withdrawal risk. A vault can only pay out what's not lent. When a market is 100% utilized, withdrawals stop until borrowers repay or are liquidated ⁸.
• Restricted legal recourse. The vault notice caps the company's liability, requires arbitration in London and excludes consumers ³.
• Small active book. Apostro's only listed Morpho vault held about $243,000 on October 23, 2026 ⁶⁷.
